1, pay attention to the power: audio equipment must have a dedicated power supply, and the power of the light is separated, and the light like a lower voltage, but the sound will have a standard voltage. After having a dedicated power supply, a stable and reliable power outlet is also required. The power supply sequencer can be used as much as possible. Although the cost increases, the stability and ease of use are improved. In short: It is crucial to properly and securely connect the power of all audio equipment. Another point to note: Some imported equipment will have a 110V and 220V selector switch in the power section. In our country, it must be confirmed that the 220V power supply can be connected only when the 220V position is selected.

2. Pay attention to the grounding of the equipment: It is very important to properly connect all audio equipments to a good ground wire. A good grounding can reduce the interference of signal transmission of the equipment and improve the stability of the equipment. It should be noted that the grounding wire should be made in accordance with the grounding standard of the lightning protection line, that is, the conductor buried in the underground part should be rust-proof, contact better, and buried deeper, and it must not be shared with the grounding wire of the three-phase power line. Not only does it reduce the noise in the sound system, it also easily damages the equipment.

3, pay attention to select the appropriate connection signal line: a sound equipment, we can use the XLR card to balance the line to connect do not use TRS balanced line connection; can use TRS balanced line connection do not use TS mono unbalanced There is no way to use TS mono unbalanced line connection equipment.

4, pay attention to the signal inversion and short circuit: the signal line short circuit often cause silent failure, check it is very troublesome, unless a signal line removed with a multimeter to detect Caixing, so be careful when welding the line.

5, pay attention to the length of the signal line: When connecting the device, we should try to use shorter signal lines, one to save costs, and second, to reduce the line resistance and interference. Under normal circumstances, the signal line with balanced transmission can reach as long as about 300 meters, while the non-balanced line can't do long-distance transmission.

6. Pay attention to the level of the device: If the +4 and -10 or -20 level switches are switched on the rear panel of the device, we normally place it at the +4 position. This is the standard level.

7. Pay attention to the pass-through: Many devices have a Bypass button. When the pass-through, the device generally does not work, so we have to pay attention to check this button, or if we let the limiter through does not work, then The device behind the compressor will lose its protective effect.

8, be careful of misuse: due to more equipment, more buttons, it is often prone to misuse, such as: There are some electronic crossover on a "× 10" button, we take care not to press it easily. For example, when our crossover point is adjusted to 200Hz, pressing this button 200 × 10 becomes 2000Hz, so we must avoid misoperation.

With good equipment, plus correct and reasonable connections, the sound system will be perfect.
